[0011] Furthermore, the maintenance vehicle is a double-station maintenance vehicle, which is arranged side by side, each station corresponds to a maintenance vehicle and a transition track, and a driving device perpendicular to the track direction is also provided at the bottom of the transition track.

[0012] Furthermore, the maintenance area includes two enclosures arranged on one side of the running track and parallel to each other, the enclosures are arranged perpendicular to the running track, two Sola doors are arranged in parallel between the two enclosures, the space formed between the two Sola doors is the maintenance area, and the transition track is located in the extended area between the two enclosures.

[0013] Furthermore, the maintenance area is provided with a guide rail cooperating with the transition track driving device, and the guide rail is used to cooperate with the transition track driving device to drive the transition track into the maintenance area.

[0014] Furthermore, the double-station maintenance vehicle is connected by a rigid connecting rod, which is used to cooperate with the guide rails alternately cooperating with the running tracks.

[0015] Furthermore, a gap with a width greater than the thickness of the Sola door is reserved between the double-station maintenance vehicles, and the guide rail is lower than the bottom of the Sola door.

[0016] Furthermore, the two shuttle doors include a manual shuttle door and an automatic shuttle door that are arranged in parallel, the automatic shuttle door is close to one side of the shuttle vehicle operation area, and the automatic shuttle door is parallel to the operation track.

The running track 5 is used to carry the shuttle 4 for normal production and transportation; the double-station maintenance vehicle 3 is parked in the shuttle operation area when the shuttle 4 is operating normally, and the track on the double-station maintenance vehicle 3 is docked and embedded with the ground running track 5, serving as a transition track and forming a complete running track with the running track 5.

[0032] The maintenance area, specifically the shuttle maintenance area, is an area for the shuttle to stop for maintenance when a malfunction occurs, and specifically includes a manual sola door 1, an automatic sola door 2, and a space surrounded by fences on both sides, and an independently controlled safety switch is installed on the manual sola door 1, and the safety switch must be turned on before the door can be opened; the specific design method is that the manual sola door 1 and the automatic sola door 2 are arranged in parallel and located between the two fences, the automatic sola door 2 is arranged close to the running track, and is used for the entry and exit of the double-station maintenance vehicle 3, the manual sola door 1 is away from the running track 5, and is used for maintenance personnel to enter the maintenance area for operation, and the area between the manual sola door 1 and the automatic sola door 2 is a maintenance area, which is designed independently from the shuttle operation area;

[0033] The double-station maintenance vehicle 3 includes two maintenance vehicles connected side by side, each maintenance vehicle is connected to a corresponding transition track, which is used for the transition track corresponding to one maintenance vehicle to be alternately engaged with the running track after one maintenance vehicle enters the maintenance area to ensure the normal operation of the running track. The displacement of the double-station maintenance vehicle 3 is carried out by a driving device arranged at the bottom of the track. The driving device in this embodiment is driven by a motor connected to a roller, but is not limited to the method of a motor driving a roller. The selection of the driving device depends on the actual situation. The driving device is also matched with a guide rail extending into the maintenance area, which is used for limiting the double-station maintenance vehicle 3, and the guide rail is lower than the bottom of the Sola door, which does not affect the opening and closing of the Sola door. The double-station maintenance vehicle 3 can accurately enter and exit the maintenance area through the limitation of the guide rail and be engaged with the transition track and the running track at the bottom.

[0034] The safety protection platform designed in this embodiment is mainly used in the maintenance stage of the maintenance area, and can also prevent illegal entry into the maintenance area to watch the operation of the shuttle vehicle during normal operation.

[0035] Example 2

[0036] A safety protection method for a shuttle vehicle specifically adopts the above safety protection platform, and the specific process is as follows:

[0037] When the shuttle is operating normally:

[0038] like Figure 1 As shown, during the normal operation stage of the shuttle vehicle 4, the manual shuttle door 1 and the automatic shuttle door 2 are in a closed state, the No. ① station track on the double-station maintenance vehicle 3 is embedded in the running track 5 as a transition track, and the maintenance vehicle drive device in this embodiment uses a mobile motor, which is normally powered but does not run, and does not affect the normal production and transportation tasks of the shuttle vehicle 4;

[0039] When the shuttle fails:

[0040] like Figure 2As shown, the dispatching system controls the shuttle vehicle 4 to run to the No. ① station of the double-station maintenance vehicle 3, and then controls the automatic sola door 2 to open, and at the same time the running track 5 is powered off. After the automatic sola door 2 is opened, the double-station maintenance vehicle 3 runs the No. ① station and the faulty shuttle vehicle to the maintenance area behind the automatic sola door 2, and the track of the No. ② station of the double-station maintenance vehicle 3 is embedded in the running track as a transition track. Finally, the automatic sola door 2 is closed, and the running track is powered on again.

[0041] Faulty shuttle repair phase:

[0042] When the shuttle car enters the maintenance area, the maintenance personnel open the safety switch on the manual shuttle door 1, and at the same time the maintenance car's moving motor is powered off to ensure that the maintenance car cannot run, and then open the manual shuttle door 1 to enter the maintenance area to repair the shuttle car; after the maintenance is completed, the maintenance personnel withdraw from the maintenance area, close the manual shuttle door 1, close the safety switch on the manual shuttle door 1, power on the maintenance car's moving motor, dispatch control automatic shuttle door 1 to open, power off the running track 5, and the maintenance car carrying the repaired shuttle car moves to the operating area until the maintenance car's No. ① station track is embedded in the running track, the shuttle car 4 returns to the running track, and then the automatic shuttle door 2 is closed, the running track is powered on, and the shuttle car continues to perform normal production and transportation tasks.

[0043] In summary, the security protection platform and protection method of the embodiments of the present invention have the following advantages:

[0044] The shuttle car maintenance system composition is redesigned to be simpler and more convenient; the shuttle car maintenance safety protection system is designed to be more rigorous, which greatly improves the safety of shuttle car maintenance; a shuttle car safety protection platform implemented in this invention eliminates the commonly used shuttle car maintenance track, and there is no need to transfer and replace the track during maintenance, which reduces the time cost of maintenance; the maintenance area is completely separated from the operation area, which improves safety while ensuring the normal operation of other equipment without affecting production efficiency.

[0045] The shuttle safety protection platform of the present invention has clear composition, clear functions, linkage in the application process and high safety. The safety protection function is mainly reflected in the maintenance area. The maintenance area layout cancels the commonly used shuttle maintenance track, and a process of transferring to the maintenance track can be omitted; the maintenance area is a completely independent space, which can be completely isolated from the shuttle operation area. During the maintenance process, the operation area can carry out production and transportation normally, and maintenance personnel can also avoid accidentally entering the operation area and being injured by the shuttle during the maintenance process.
